When the port of the cylinder is released, the load generated by the weight acts as a load to pull up the rod, allowing the cylinder to be tested for extension. When the cylinder is extended, a pair of pulleys attached to the rod are positioned above the line, and the port of the cylinder is released, a load is applied to the rope to push down the rod, testing the contraction of the cylinder. can be done.

を行なえる。 The cylinder is tested by connecting pumps, valves, pressure gauges, etc. By arranging the cylinder so that the middle of the cylinder's maximum stroke is located on the line connecting the pair of fixed pulleys and the fixed end, an extension test of the contracted cylinder was performed at half the maximum stroke and the cylinder was extended. A cylinder reduction test can be performed during the remaining half of the stroke. If the pair of fixed pulleys in the middle of the rope and the fixed end of the rope are configured to be movable relative to the cylinder, an expansion/contraction test can be performed over the entire stroke of the cylinder.
